A colleague and I will revise the syllabus for our university's course "Foundations of Geometry" this Fall. The course presents an axiomatic foundation of Euclidean and non-Euclidean geometries while covering the basics of axiomatic systems and how to formulate and write proofs. This course is required for secondary math education majors and, for the most part, these are the only students in the course. I would like to revise the syllabus with the eventual needs of these students in mind.

So, here are the big questions: Now that you are teaching geometry, what would you have liked to learn in the course "Foundations of Geometry" or its equivalent? What did you find most useful in the course you took? Least useful? And so on. I am open to radical suggestions.
